Abstract
The present disclosure relates to a method for transmitting duplicated data units by considering measurement gap in a wireless communication system. In particular, the method includes the steps of: generating a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel; and transmitting the MAC PDU based on there being no measurement gap at the time of the transmission, wherein, based on there being the measurement gap at the time of the transmission, a Packet Data Convergence Protocol (PDCP) duplication of a Radio Bearer (RB) related to the logical channel is activated.
Claims10
A method comprising:
- obtaining, by a User Equipment (UE), a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel;
- and
- performing, by the UE, a transmission of the MAC PDU according to a configured uplink grant based on there being no measurement gap at a time of the transmission of the MAC PDU according to the configured uplink grant,
- wherein, based on there being the measurement gap at the time of the transmission of the MAC PDU according to the configured uplink grant, the transmission of the MAC PDU is skipped and a Packet Data Convergence Protocol (PDCP) duplication for a Radio Bearer (RB), to which the logical channel belongs, is activated.
A user equipment (UE) comprising:
- at least one processor;
- and
- at least one computer memory storing instructions that, when executed by the at least one processor, cause the UE to perform operations comprising:
- obtaining a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel;
- and
- performing a transmission of the MAC PDU according to a configured uplink grant based on there being no measurement gap at a time of the transmission of the MAC PDU according to the configured uplink grant,
- wherein, based on there being the measurement gap at the time of the transmission of the MAC PDU according to the configured uplink grant, the transmission of the MAC PDU is skipped and a Packet Data Convergence Protocol (PDCP) duplication for a Radio Bearer (RB), to which the logical channel belongs, is activated.
An apparatus for a user equipment (UE), the apparatus comprising:
- at least one processor;
- and
- at least one computer memory storing instructions that, when executed by the at least one processor, cause the UE to perform operations comprising:
- obtaining a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel;
- and
- performing a transmission of the MAC PDU according to a configured uplink grant based on there being no measurement gap at a time of the transmission of the MAC PDU according to the configured uplink grant,
- wherein, based on there being the measurement gap at the time of the transmission of the MAC PDU according to the configured uplink grant, the transmission of the MAC PDU is skipped and a Packet Data Convergence Protocol (PDCP) duplication for a Radio Bearer (RB), to which the logical channel belongs, is activated.
A non-transitory computer readable storage medium comprising program instructions that, when executed by at least one processor, cause a user equipment (UE) to perform operations comprising:
- obtaining a Medium Access Control (MAC) Protocol Data Unit (PDU) containing a MAC Service Data Unit (SDU) associated with a logical channel;
- and
- performing a transmission of the MAC PDU according to a configured uplink grant based on there being no measurement gap at a time of the transmission of the MAC PDU according to the configured uplink grant,
- wherein, based on there being the measurement gap at the time of the transmission of the MAC PDU according to the configured uplink grant, the transmission of the MAC PDU is skipped and a Packet Data Convergence Protocol (PDCP) duplication for a Radio Bearer (RB), to which the logical channel belongs, is activated.
